TWIN RELEASE

The TWIN RELEASE is a double pulley with a locking function from Petzl, perfect for building 4:1 hauling systems in confined spaces or for technical rescue. Its ergonomic design with integrated brake provides excellent control when lowering heavy loads up to 280 kg.

Detailed description

The TWIN RELEASE is a removable double progress capture pulley optimized for 4:1 hauling systems. With an ergonomic handle for easy cam release, an integrated brake in the movable side plate, and a main pulley with unidirectional rotation, you get better braking and control during lowering. The double pulleys provide high hauling efficiency. The swivel facilitates handling by allowing the pulley to rotate under load and enabling direct attachment of carabiners, ropes, or slings.

Features

• Double progress capture pulley with cam release handle: Ergonomic handle for easy cam release.
• Brake integrated into the main movable side plate for convenient and precise control when lowering heavy loads.
• The cam can be locked in the open position for easy slack feeding.
• Toothless cam protects the rope and allows for smooth transition between lowering and hauling.
• Optimized efficiency for 4:1 hauling systems: Large pulley diameter on sealed ball bearings for high hauling efficiency (95%).
